Menahem son of Gadi began to rule over Israel in the thirty-ninth year of King Uzziah's reign in Judah. He reigned in Samaria ten years.
But Menahem did what was evil in the LORD's sight. During his entire reign, he refused to turn from the sins of idolatry that Jeroboam son of Nebat had led Israel to commit.
Then King Tiglath-pileser of Assyria invaded the land. But Menahem paid him thirty-seven tons of silver to gain his support in tightening his grip on royal power.
